PIPE.

Application tiled March 21, 1917.

structions, combinations, and arrangements herein described and claimed.

An object ot' my invention is to provide a smoking pipe embodying` a.novel nicotin collecting vessel and an insertible smoke cooling memberincluding a spiral groove whereby the nicotin is received in the vesseland the -smoke is cooled while passing V.through the groove.

Another object of the invention is to provide a smoking pipe includingthe elements and features above enumerated, the construction ot' thepipe permitting ready disassembling for cleaning.

Other objects and advantages will appear from the followingspecification, ret'- erence being had to the accompanying drawing inwhich:

Figure 1 is a central longitudinal section of a pipe illustrating thenicotin collecting vessel in section and the smoke cooling member inelevation.

Fig. 2 is a section on the line 2--2 et Fig. 1, and

Fig. 3 is an inverted perspective view of the nicotin receiving vessel.

In carrying` out one of the features ot my invention, it will beobserved that I provide a cylindrical plug 1. The plug 1 has a spiralgroove 2 formed in its periphery or Surface as illustrated in Fig. 1.The cylindrical plug 1 is insertible in the bore 3 ot the pipe stem Apassage (i establishes' communications between the bowl 5 and the bore 3of the Stem 4, a shoulder 7 being formed at the juncture of the passage6 and bore 3 adjacent which the cylindrical plug 1 rests when the partsare assembled.

The. outer endot the spiral groove 2. of the cylindrical plug 1terminates coaxially of the plug 1 and is internally screw threaded asindicated at S. A screw block J is screwed into engagement with thescrew threaded portion S and includes an enlarged threaded portion onwhich the mouth piece, i0 of the pipc is screwed. 'lhe .screw block 9has a Speaeication of Letters Patent.

)i which is integral with thevv Patented Jan. 14, 1919.

Serial No. 156,351.

'with the spiral groove 2 as plainly shown in the drawings7 the smokebore in the screw vplug 9 also communicating with the bore l0 in themouth piece 10 when the parts are assembled as shown in Fig, 1.

A nieotin receiving vessel 11 is located at the bottom of the bowl 5adjacent to the passage 6. The vessel 11 includes a drumlike upperportion 12 which has a plurality ot' -perforations 13. That portion ofthe vessel 11 adjacent to the drum-like upper portion l2 is ot' a largerdiameter than Athe main drum-like portion thereof. It will be seen thatthe portion 12 is of such dimensions that it snugly engages the lowerpor tion of the bowl 5. The portion 14C of the vessel 11 has a laterallyextending neck 15 which is adapted to be projected into the passage fl.The neck 15 has anupwardly curved beak 16 lwhich is projected into theinner end of the spiral. groove il ot the cylindrical plug 1. For thepurpose et accomplishing the connections above referred to, the spiralgroove 2 terminates coaXially of the cylindrical plug 1 at the placeadjacent the connection with the beak 16.

The construction ot the pipe having been explained, the method ofassembling the parts is as follows: Assuming the various parts abovedescribed are to be disasiembled, the cylindrical plug 1 is inserted inthe bore 3 of the pipe stem 4. The nicotin receiving vessel 11 is nowplaced within the bowl 5 of the pipe and adjusted until the beak 16enters the inner end of the spiral groove Z adjacent to the shoulder 7.

The connections betweenthe receptacle 11 and the cylindrical plug 1having been made.-

the mouth piece 1() is screwed onto the screw block 9 until it tightlybinds against the adjacent end of the pipe stem 4i. It will be observedthat the upwardly curved beak 16 frorns the binding member which holdsthe cylindrical plug i and the mouth piece 10' againstaccidentaldisplacement.

In the use ot the pipe the nicotin from the tobacco contained in thebowl 5 will be col'- lec-tcd in the vessel. It will be noted that thebeak 16 branches from the neck 15 at. a. place adjacent.` the upperportion thereof. lVhen it becomes necessary to oleanthe pipe. the mouthpiece 10 is removed so that the cylindrical plug member may subseine' ahollow stein tures formed therein, fuse to pass into said vessel, a neckextend- .quently be removed. The veesel ll is then taken from the bowlby turning it in such a I nanner that the beak'l disengagee the ing fromsaid dru1n-like lower portion in a plane below the drum-like upperportion, an 20 upwardly curved beak formed upon the outer end of saidneck in a plane above the bottom of said neck, and means carried withinsaid hollow stein and engaging said beak for holding said nicotinreceiving vessel against accidental displacement, said means bearingupon said shoulder for iimly holding said vessel and said means inrespective position.

In testimony whereof I aliX my signature 30 in presence of twoWitnesses.
